Greetings,

I have reviewed several heater box removal threads and was hoping to get the info I needed from them and not have to bother anyone with another posting on this topic. Well I have hit a minor snag and just wanted to make sure that I am interpreting things correctly.

I believe that LILRED66 mentioned in a prior posting that in addition to removing the 5 hex lag bolts that secure the box to the frame, one has to also remove 2 speed nuts from inside the cab.

I have removed the engine bay lag bolts. The right side of the unit (as I face the front of the truck) appears free. I can see a threaded bolt trying pull out of the back right side of the box which is coming from through the firewall. So my gut is telling me nothing was actually holding that bolt in place.

The left side is different. Something is clearly preventing the left side of the box from freeing up to be pulled out. So I am thinking there is some kind of similar nut/bolt on that side. Am I right here? Just wanted to verify that on a 64 there are two speed nuts or bolts or something that I have to undo. If this is right just let me know.

I must be blind since I am not seeing this left side nut/bolt when I get inside the cab. Given the firewall insulation pad I installed a few months ago, I am wondering if the padding is covering the bolt/nut from the inside. I have started to pull back the padding to see what I can find and will continue to do so.

I also undid the 3 small hex bolts used to mount the inside defroster/heater unit to the inside portion of the firewall. I figured that was not going to resolve my problem. And of course it did not.

Any advice would be appreciated. I hope to avoid peeling back too much of my insulation.
